Flyback voltage measured against 0 V; for TDA4865J only.
(1) With C
(2) With R5 capacitor C
(3) R6 reduces the power dissipation of the IC. The maximum possible value depends on the application.
Remark: the heat sink of the IC must be isolated against ground of the application (it is connected to pin GND).
